Companding
Companding, also known as compansion, comes from the combination of compressing and expanding, which is a method of reducing the effects of a channel with limited dynamic range. The use of companding allows signals with a large dynamic range to be transmitted over facilities that have a smaller dynamic range capability. Companding reduces the noise and crosstalk levels at the receiver.
